440C Stainless Hlau Ca Bar
Cov lus piav qhia luv luv:
S44000 lub tiaj tiaj tus kab, SS 440 pav ca, stainless hlau 440 tiaj tus hlau 440 ca cov chaw muag khoom, chaw tsim tshuaj paus thiab tus xa khoom hauv Suav teb.
Stainless cov hlau yog cov high-alloy steels uas muaj cov kev tiv thaiv zoo piv rau lwm cov hlau vim muaj cov roj chomium ntau. Raws li lawv cov qauv crystalline, lawv tau muab faib ua peb hom xws li ferritic, thiab cov ntaus pob martensitic, thiab cov ntaus nrig ntaus nrig. Lwm pab pawg ntawm stainless cov hlau yog nag lossis daus-hardened hlau. Lawv yog kev sib xyaw ua ke ntawm Martensitic thiab Austenitic cov hlaus. Qeb 440C stainless hlau yog cov pa roj carbon martensitic stainless hlau. Nws muaj lub zog muaj zog, nruab nrab corrosion tsis kam, thiab zoo hardness thiab hnav tsis kam. Qeb 440C muaj peev xwm ua tau, tom qab kev kho cua sov, lub zog siab tshaj plaws, hardness thiab hnav tsis kam ntawm txhua qhov stainless alloys. Nws cov ntsiab lus carbon ntau heev yog lub luag haujlwm rau cov yam ntxwv no, uas ua rau 440c tshwj xeeb haum rau cov ntawv thov raws li pob kabmob thiab lub valve.
